“Can a no-code automated trading platform become the go-to investment OS for retail algo traders by abstracting away both strategy-building complexity and brokerage infrastructure?”
Founded in 2020 as a no-code automated trading platform for retail investors, Composer allows users to build, backtest, and deploy algorithmic investment strategies called Symphonies without writing code. The company established its own broker-dealer (Composer Securities LLC) and relies on Alpaca Securities and Apex Clearing as clearing partners rather than building its own clearing infrastructure. Over time it expanded from individual taxable brokerage accounts to IRAs, added an API layer for programmatic access, and integrated KYC provider Footprint and open-banking aggregator Plaid to streamline onboarding and funding.
Composer discloses Alpaca as its banking provider, according to the Embedded Finance Index 2026.
Composer does not disclose a bank charter of its own; its banking services are provided through Alpaca.
Composer moves money over ACH and Wire.
Composer connects to bank accounts through Plaid.
The Embedded Finance Index 2026 maps 3 layers in Composer's stack: Money movement (ACH and Wire); Banking / BaaS (Alpaca); Open banking (Plaid).
Composer is founded in 2020 and headquartered in Toronto, Ontario, Canada.
